combinations of gravimetric and
opacimetric filters
MFVA module
Free-cooling module (optional)
with built-in plug-fan and posibility
of cooling recovery circuit
Unit components
Outdoor unit 38NZ/NF
■■ Outdoor air circuit
-- Centrifugal fan coupling by pulleys and belts. Electric
motor(s) with tensioner, class F, IP55 and internal
thermal protection. One double-intake turbine, with an
impeller with front-curved blades. Greased spherical
bearings, with no maintenance required.
-- Coil(s) with copper pipes and aluminium fins.
-- Condensates drain pan.
■■ Cooling circuit
-- Hermetic scroll-type compressor(s), assembled over
antivibration mounts. Control of phase equilibrium and
the direction of rotation.
-- Crankcase heater.
-- Therm ostatic expansion valve with external
equalisation (heat pump units).
-- Four-way cycle reversing valves (heat pump units).
-- Particle separator(s), anti-acid dehydrating filter(s),
liquid receiver(s).
-- Cooling connections for welding.
-- Maximum equivalent length of the cooling line 50
metres (for longer distances an oil separator must be
used).
■■ Electric panel
-- Complete and fully wired electric panel. Insulated
panel cover to prevent condensation. Protection IP55.
-- Transformer for power supply without neutral included
in the electrical panel.
-- Main ground connection.
-- Compressor(s) and fan(s) motor contacts.
AIR TREATMENT
-- C
asing made of galvanised steel metal with polyester
paint, white colour RAL 7035. Self-supporting frame.
■■ Protections
-- High and low pressure pressostats.
-- Compressor discharge temperature control.
-- Non-return valve built into the compressor.
-- Main door switch.
-- Magnetothermic protection switches for the
compressor(s) power line and fans motor.
-- Automatic switch in the control circuit.
